  • the US 2012/0132767 A1 shows an improved system having resiliently moveable linkage arms and rods extending vertically from the base to the table top. This prevents the parts from being destroyed in the event of emergency braking. In addition, the risk of injuries is further reduced. The disadvantage, however, is that the passengers' body parts can be crushed because the height of the tabletop changes during movement.
  • the object is therefore to provide a table of the type mentioned which has a reduced risk of injury to passengers when strong accelerations occur. Up to a certain load limit, only one reversible Deformation occur, ie that the table automatically returns to its original position.
  • the connecting device has at least one elastic connecting bar which extends essentially along the longitudinal axis and via which the tabletop is connected to the base.
  • a purely or predominantly horizontal movement of the table top can be achieved by such an arrangement of a connecting beam. This reduces the risk of passenger injury.
  • the arrangement is particularly advantageous since the connecting beam can be arranged directly below the table top, which saves space and is thus better protected against damage or vandalism.

  • the connecting beam is connected to the table top at its ends and is connected to the base in a central fastening area between the ends.
  • the central attachment area is preferably connected to the substructure, if provided. This is particularly advantageous because it means that both sides of the tabletop can be well sprung.

Description

Die Erfindung betrifft einen Tisch für ein Fahrzeug, wobei der Tisch zumindest einen Sockel zur Befestigung an dem Fahrzeug, sowie eine mit dem Sockel verbundene Tischplatte aufweist, und wobei die Tischplatte über eine Verbindungsvorrichtung in Bezug zum Sockel quer zu einer Längsachse des Tisches elastisch bewegbar ist.The invention relates to a table for a vehicle, the table having at least one base for attachment to the vehicle and a table top connected to the base, and the table top being elastically movable transversely to a longitudinal axis of the table in relation to the base via a connecting device .

In Fahrzeugen, insbesondere Schienenfahrzeugen, ist es für Fahrgäste üblich, Tische anzuordnen, welchen normalerweise insgesamt vier Sitzplätze zugeordnet sind. Dabei sind in der Regel zwei Sitzplätze nebeneinander in Fahrtrichtung und zwei gegenüberliegende entgegen der Fahrtrichtung gerichtet und der Tisch dazwischen angeordnet. Dementsprechend ist die Längsachse des Tisches üblicherweise quer zur Fahrtrichtung des Fahrzeugs ausgerichtet.In vehicles, particularly rail vehicles, it is customary for passengers to arrange tables, which are normally assigned a total of four seats. As a rule, two seats are next to each other in the direction of travel and two opposite ones are directed against the direction of travel and the table is arranged in between. Accordingly, the longitudinal axis of the table is usually aligned transversely to the direction of travel of the vehicle.

Dabei ist mit Fahrtrichtung die Hauptfahrrichtung des Fahrzeuges gemeint, in die sich das Fahrzeug in der Regel hauptsächlich bewegt. In den allermeisten Fällen ist dabei die Fahrtrichtung parallel zur Längsachse des Fahrzeugs.The direction of travel here means the main direction of travel of the vehicle, in which the vehicle usually mainly moves. In most cases, the direction of travel is parallel to the longitudinal axis of the vehicle.

Zum Schutz der Passagiere, die auf den Sitzen in Fahrtrichtung sitzen, kann der Tisch einen Energieabsorptionsmechanismus aufweisen. Beim Auftreten von starken Beschleunigungen, beispielsweise im Falle einer Notbremsung oder eines Zusammenstoßes wird dabei die Bewegungsenergie der auf den Tisch aufprallenden Fahrgäste zumindest teilweise absorbiert und deren Verletzungsrisiko verringert.In order to protect the passengers sitting on the front-facing seats, the table may have an energy absorption mechanism. When strong acceleration occurs, for example in the event of emergency braking or a collision, the kinetic energy of the passengers hitting the table is at least partially absorbed and their risk of injury is reduced.

Die EP 2 956 347 B1 beschreibt einen Tisch mit plastisch verformbaren Verbindungselementen, die sich bei einem Aufprall plastisch verformen und so Energie absorbieren. Dies ist aber unvorteilhaft, da nach einem derartigen Vorfall wesentliche Teile des Tisches ausgetauscht werden müssen, um diesen wieder funktionsfähig zu machen. Die damit verbundenen Arbeiten sind aufwändig und teuer.the EP 2 956 347 B1 describes a table with plastically deformable connecting elements that deform plastically on impact and thus absorb energy. This is disadvantageous, however, since after such an incident, essential parts of the table have to be replaced in order to make it functional again. The associated work is time-consuming and expensive.

Die US 2012/0132767 A1 zeigt ein verbessertes System, das elastisch bewegliche Verbindungsarme und -stangen aufweist, die sich vom Sockel vertikal zur Tischplatte erstrecken. Dadurch wird die Zerstörung der Teile bei einer Notbremsung verhindert. Darüber hinaus wird das Risiko von Verletzungen weiter vermindert. Nachteilig ist jedoch, dass es zu Quetschungen von Körperteilen der Fahrgäste kommen kann, da sich die Höhe der Tischplatte bei der Bewegung ändert.the US 2012/0132767 A1 shows an improved system having resiliently moveable linkage arms and rods extending vertically from the base to the table top. This prevents the parts from being destroyed in the event of emergency braking. In addition, the risk of injuries is further reduced. The disadvantage, however, is that the passengers' body parts can be crushed because the height of the tabletop changes during movement.

Aufgabe ist damit, einen Tisch der genannten Art bereitzustellen, der ein verringertes Verletzungsrisiko für Fahrgäste bei Auftreten starker Beschleunigungen aufweist. Dabei soll bis zu einer bestimmten Belastungsgrenze nur eine reversible Verformung auftreten, d.h., dass der Tisch selbsttätig in seine Ausgangslage zurückkehrt.The object is therefore to provide a table of the type mentioned which has a reduced risk of injury to passengers when strong accelerations occur. Up to a certain load limit, only one reversible Deformation occur, ie that the table automatically returns to its original position.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Verbindungsvorrichtung zumindest einen, sich im Wesentlichen entlang der Längsachse erstreckenden, elastischen Verbindungsbalken aufweist, über den die Tischplatte mit dem Sockel verbunden ist.This object is achieved according to the invention in that the connecting device has at least one elastic connecting bar which extends essentially along the longitudinal axis and via which the tabletop is connected to the base.

Durch eine derartige Anordnung eines Verbindungsbalkens kann eine rein oder überwiegend horizontale Bewegung der Tischplatte erreicht werden. Dadurch wird die Gefahr von Verletzungen durch den Fahrgast verringert. Die Anordnung ist besonders vorteilhaft, da der Verbindungsbalken direkt unterhalb der Tischplatte angeordnet werden kann, was platzsparend ist und er so vor Beschädigung oder Vandalismus besser geschützt ist.A purely or predominantly horizontal movement of the table top can be achieved by such an arrangement of a connecting beam. This reduces the risk of passenger injury. The arrangement is particularly advantageous since the connecting beam can be arranged directly below the table top, which saves space and is thus better protected against damage or vandalism.

Dabei sind Richtungs- oder Orientierungsangaben wie oben oder horizontal auf eine bestimmungsgemäße Einbaustellung des Tisches in einem Fahrzeug bezogen.In this case, directional or orientation information such as above or horizontally relates to an intended installation position of the table in a vehicle.

Die Verbindungsvorrichtung kann über den Verbindungsbalken hinaus weitere elastisch verformbare Elemente aufweisen, die die Energieaufnahme verbessern. Dabei können diese Elemente seriell zum Verbindungsbalken oder parallel zu ihm geschalten sein.In addition to the connecting bar, the connecting device can have other elastically deformable elements that improve the energy absorption. These elements can be connected in series with the connecting bar or in parallel with it.

Besonders vorteilhaft ist, wenn der Sockel mit einem sich im Wesentlichen entlang der Längsachse erstreckenden Unterbau fest verbunden ist und die Tischplatte auf dem Unterbau elastisch bewegbar angeordnet ist. Der Unterbau kann so ausgeführt sein, dass der Verbindungsbalken darin - geschützt vor unbefugter Manipulation - angeordnet werden kann. Die Tischplatte kann beweglich auf dem Unterbau angeordnet sein und auf ihm ruhen. Dabei kann der Unterbau und der Sockel auch einstückig ausgeführt sein. Vorzugsweise ist der Unterbau quer zur Längsachse weniger breit ausgeführt, als die Tischplatte. Dies ermöglicht eine Bewegung der Tischplatte quer zur Längsrichtung, auch wenn sie den Unterbau an ihren Seitenkanten zumindest teilweise überragt.It is particularly advantageous if the base is firmly connected to a substructure that extends essentially along the longitudinal axis and the table top is arranged on the substructure in an elastically movable manner. The substructure can be designed in such a way that the connecting beam can be arranged in it—protected against unauthorized manipulation. The table top can be movably arranged on the base and rest on it. The substructure and the base can also be made in one piece. The substructure is preferably designed to be less wide transversely to the longitudinal axis than the table top. This allows the tabletop to move transversely to the longitudinal direction, even if it at least partially protrudes beyond the substructure at its side edges.

Weiters kann vorgesehen sein, dass der Verbindungsbalken an seinen Enden mit der Tischplatte verbunden ist und in einem mittleren Befestigungsbereich zwischen den Enden mit dem Sockel verbunden ist. Dabei ist der mittlere Befestigungsbereich vorzugsweise mit dem Unterbau verbunden, falls vorgesehen. Dies ist besonders vorteilhaft, da dadurch beide Seiten der Tischplatte gut gefedert werden können. Insbesondere bei Tischen, an denen an einer Seite zwei Plätze für Personen vorgesehen sind, ist dies wichtig. Sind beide Plätze vergeben und treffen beide Personen bei einem Zusammenstoß auf die gleiche Tischseite, so bewegen sich beide Hälften der Tischplatte im Wesentlichen in die gleiche Richtung. Sind die Personen gleich schwer, so kommt es in etwa zu einer parallelen Verschiebung der Tischplatte. Ist nur ein Platz besetzt, so kommt es zu einer Verdrehung der Tischplatte.Furthermore, it can be provided that the connecting beam is connected to the table top at its ends and is connected to the base in a central fastening area between the ends. In this case, the central attachment area is preferably connected to the substructure, if provided. This is particularly advantageous because it means that both sides of the tabletop can be well sprung. This is particularly important for tables where there are two places for people on one side. If both seats are taken and both people collide on the same side of the table, both halves of the table top move essentially in the same direction. Are the If people are of the same weight, the table top will be shifted approximately parallel. If only one seat is occupied, the table top twists.

In einer bevorzugten Ausführung ist vorgesehen, dass die Verbindungsvorrichtung zumindest ein elastisch verformbares Sekundärelement aufweist. Dieses Sekundärelement kann beispielsweise als vorzugsweise gefederter Stoßdämpfer ausgeführt sein und mit der elastischen Verformung des Verbindungsbalkens zusammenwirken, ihn beispielsweise dämpfen.In a preferred embodiment it is provided that the connecting device has at least one elastically deformable secondary element. This secondary element can be designed, for example, as a preferably spring-loaded shock absorber and interact with the elastic deformation of the connecting beam, for example dampening it.

Weiter kann vorgesehen sein, dass das elastisch verformbare Sekundärelement parallel zum Verbindungsbalken zwischen der Tischplatte und dem Sockel geschaltet ist. Dabei ist gemeint, dass zumindest zwei Verbindungswege zwischen Tischplatte und Sockel existieren: einer über den Verbindungsbalken und einer über das Sekundärelement. Damit wirken die elastischen Verformungen dieser beiden verformbaren Bauteile parallel und nicht seriell. Alternativ können sie auch seriell zueinander geschalten sein. Dabei muss das Sekundärelement nicht über den gesamten Bewegungsraum der Tischplatte Energie aufnehmen. Es kann auch beispielsweise vorgesehen sein, dass das Sekundärelement einen Leerlauf aufweist und erst ab einem bestimmten Grad an Verschiebung zwischen Tischplatte und Sockel Energie aufnimmt.It can further be provided that the elastically deformable secondary element is connected parallel to the connecting beam between the table top and the base. This means that there are at least two connection paths between the table top and the base: one via the connecting beam and one via the secondary element. The elastic deformations of these two deformable components thus act in parallel and not in series. Alternatively, they can also be connected in series with one another. The secondary element does not have to absorb energy over the entire range of movement of the table top. Provision can also be made, for example, for the secondary element to have an idle state and only absorb energy from a certain degree of displacement between the table top and the base.

Wenn vorgesehen ist, dass das Sekundärelement zwei gegeneinander elastisch verschiebbare Endstücke aufweist und sich diese Endstücke an zwei gegenüberliegenden Auflageflächen des Unterbaus abstützen, und dass zumindest ein Endstück über zumindest ein Auflagestück mit der Tischplatte in Verbindung steht, so kann die Tischplatte beweglich gelagert werden, während das Sekundärelement Energie aufnimmt. Ist an beiden Endstücken je zumindest ein Auflagestück vorgesehen, so kann die Tischplatte in zwei Richtungen elastisch beweglich gelagert werden. Dabei sind die Auflageflächen vorzugsweise entlang einer Achse einander gegenüberliegend angeordnet, wobei die Achse quer zur Längsachse steht. Die Verbindung mit der Tischplatte muss nicht in allen Positionen der Tischplatte für das Auflagestück gegeben sein. Bei Bewegung der Tischplatte in eine Richtung wird über ein Auflagestück ein erstes Endstück in Richtung des zweiten Endstücks gedrückt, welches auf der Auflagefläche aufliegt und sich daran abstützt. Bei Bewegung in die entgegengesetzte Richtung wird das Auflagestück, das mit dem zweiten Endstück verbunden ist, in Richtung des ersten Endstücks gedrückt, das wiederum auf der anderen Auflagefläche aufliegt.If it is provided that the secondary element has two end pieces that can be displaced elastically in relation to one another and these end pieces are supported on two opposite bearing surfaces of the substructure, and that at least one end piece is connected to the table top via at least one bearing piece, the table top can be movably mounted while the secondary element absorbs energy. If at least one support piece is provided on each of the two end pieces, the tabletop can be mounted so that it can move elastically in two directions. The bearing surfaces are preferably arranged opposite one another along an axis, the axis being transverse to the longitudinal axis. The connection with the table top does not have to be given in all positions of the table top for the support piece. When the table top moves in one direction, a first end piece is pressed in the direction of the second end piece via a support piece, which end piece rests on the support surface and is supported on it. When moving in the opposite direction, the support piece, which is connected to the second end piece, is pushed towards the first end piece, which in turn rests on the other support surface.

Besonders vorteilhaft ist, wenn ein mit der Tischplatte verbundenes Verbindungsstück quer zur Längsachse vor oder hinter von zumindest einem mit dem Sekundärelement verbundenen Auflagestück angeordnet ist und dass im unbelasteten Zustand der Tischplatte das Verbindungsstück vom Auflagestück beabstandet ist. Dadurch wird der Tischplatte ein Bewegungsspielraum eröffnet, in dem sich das Sekundärelement nicht elastisch verformt. Vorzugsweise tritt in diesem Bereich aber trotzdem zumindest teilweise eine elastische Verformung des Verbindungsbalkens auf. Erst bei einer Bewegung über diesen Spielraum hinaus tritt eine elastische Verformung des Sekundärelements auf.It is particularly advantageous if a connecting piece connected to the table top is arranged transversely to the longitudinal axis in front of or behind at least one supporting piece connected to the secondary element and that in the unloaded State of the table top, the connector is spaced from the support piece. This opens up a range of motion for the tabletop, in which the secondary element does not deform elastically. Preferably, however, an elastic deformation of the connecting bar occurs at least partially in this area. An elastic deformation of the secondary element only occurs when there is a movement beyond this clearance.

Es kann vorgesehen sein, dass quer zur Längsachse auf beiden Seiten vom Verbindungsstück und in unbelastetem Zustand beabstandet je ein Auflagestück angeordnet ist. Dadurch kann die elastische Verformung des Sekundärelements ab Überschreiten des Bewegungsspielraumes in beide Richtungen erfolgen. Dies ist besonders vorteilhaft, da insbesondere Zugwaggons oft entlang ihrer Hauptachse in beide Richtungen geführt werden. Dazu ist irrelevant, in welcher Richtung der Tisch eingebaut wird, da er in beide Richtungen elastisch verformbar ist.Provision can be made for a support piece to be arranged transversely to the longitudinal axis on both sides of the connecting piece and spaced apart in the unloaded state. As a result, the elastic deformation of the secondary element can take place in both directions once the range of motion is exceeded. This is particularly advantageous since train wagons in particular are often guided in both directions along their main axis. It is irrelevant in which direction the table is installed, since it can be elastically deformed in both directions.

Platzsparend ist es, wenn das zumindest eine Verbindungsstück an zumindest einem Ende des Verbindungsbalkens angeordnet ist. Dadurch kann das Verbindungsstück dual zur Verbindung mit dem Verbindungsbalken und zur Verbindung mit dem Sekundärelement verwendet werden.It is space-saving if the at least one connecting piece is arranged at at least one end of the connecting beam. This allows the connector to be used dual to connect to the connector beam and to connect to the secondary element.

Wenn der Verbindungsbalken zumindest eine Blattfeder aufweist, vorzugsweise als Blattfederpaket ausgeführt ist, so kann damit eine gute elastische Bewegbarkeit erreicht werden. Die Blattfeder ist vorzugsweise so angeordnet, dass die federnde Hauptwirkungsrichtung in bestimmungsgemäßer Einbaustellung quer zur Längsachse und im Wesentlichen horizontal liegt. Der Vorteil eines Blattfederpakets liegt in der Eigendämpfung, die in Hinblick auf die Energiedissipation vorteilhaft ist.If the connecting beam has at least one leaf spring, preferably in the form of a leaf spring assembly, good elastic mobility can be achieved. The leaf spring is preferably arranged in such a way that the resilient main direction of action lies transversely to the longitudinal axis and essentially horizontally in the intended installation position. The advantage of a leaf spring assembly lies in its self-damping, which is advantageous in terms of energy dissipation.

Besonders vorteilhaft ist, wenn die Tischplatte entlang der Längsachse im Wesentlichen mittig einen Verbindungsstift aufweist, der mit einem Schlitten des Unterbaus verbunden ist, und dass der Schlitten quer zur Längsachse beweglich zum Unterbau ist. Dies ermöglicht eine bewegliche Lagerung der Tischplatte quer zur Längsachse. Der Schlitten kann elastisch bewegbar sein, beispielsweise gefedert sein oder auch hauptsächlich zur Führung der Tischplatte dienen und nicht oder nur in sehr untergeordnetem Maße zur Energieaufnahme beitragen.It is particularly advantageous if the tabletop has a connecting pin essentially centrally along the longitudinal axis, which is connected to a carriage of the substructure, and that the carriage can be moved transversely to the longitudinal axis with respect to the substructure. This enables the tabletop to be flexibly mounted transversely to the longitudinal axis. The carriage can be elastically movable, for example spring-loaded, or also serve primarily to guide the tabletop and contribute only to a very minor extent, if at all, to energy absorption.

Wenn vorgesehen ist, dass der Unterbau zumindest ein Reibelement aufweist, das gefedert an der Tischplatte anliegt, so kann eine zusätzliche Dämpfung der Bewegung der Tischplatte zum Unterbau erreicht werden.If it is provided that the substructure has at least one friction element which bears against the table top in a spring-loaded manner, additional damping of the movement of the table top relative to the substructure can be achieved.

Es kann vorgesehen sein, dass der Unterbau zumindest ein Tischbein aufweist, das mit einem Fahrzeugboden verbindbar ist. Dies ermöglicht eine besonders gute Verbindung mit dem Fahrzeug. Abhängig von der Länge des Beines kann der Tisch in unterschiedlichen Höhen befestigt werden.Provision can be made for the substructure to have at least one table leg which can be connected to a vehicle floor. This enables a particularly good connection to the vehicle. Depending on the length of the leg, the table can be fixed at different heights.

Besonders vorteilhaft ist, wenn der Sockel mit einer Fahrzeugwand des Fahrzeugs verbindbar ist. Insbesondere die seitliche Befestigung an einer Seitenwand des Fahrzeuges ist vorteilhaft.It is particularly advantageous if the base can be connected to a vehicle wall of the vehicle. In particular, lateral attachment to a side wall of the vehicle is advantageous.

In der Folge wird die vorliegende Erfindung anhand einer in den Figuren dargestellten nicht einschränkenden Ausführungsvariante näher erläutert. Es zeigen:

The present invention is explained in more detail below with reference to a non-limiting embodiment variant shown in the figures. Show it:

Figure 12 shows an exploded view of the base of the embodiment 1 ;

a detail of the substructure in a plan view.

Fig. 1 zeigt einen erfindungsgemäßen Tisch 1 mit einer im Wesentlichen rechteckigen Tischplatte 2 und einem Sockel 3. Der Tisch 1 ist in einem teilweise dargestellten Fahrzeug, hier eines Zugwaggons, an einer Fahrzeugseitenwand 100 des Fahrzeugs angeordnet. Eine Längsachse A des Tisches 1 erstreckt sich parallel zu den längeren Seitenkanten 4 der Tischplatte 2 und liegt quer zu einer Fahrtrichtung 101 des Fahrzeugs. Der Sockel 3 weist ein im Wesentlichen vertikalen, an der Fahrzeugseitenwand 100 anliegenden Wandteil 5 und einen Unterbau 6 direkt unterhalb der Tischplatte 2 auf. Die Tischplatte 2 überragt an den Seitenkanten 4 den Unterbau 6 abschnittsweise und bildet damit an jeder Seite zwei verbreitete Aufprallflächen 7. An beiden Seitenkanten 4 der Tischplatte sind je zwei Sitzplätze 102 angeordnet, zwei in und zwei gegen die Fahrtrichtung 101. Dabei sind die Aufprallflächen 7 entlang der Fahrtrichtung 101 direkt vor den Sitzplätzen 102 angeordnet und bieten so eine größere Fläche, an denen Fahrgäste im Falle eines Zusammenstoßes auf dem Tisch 1 aufprallen können. 1 shows a table 1 according to the invention with an essentially rectangular table top 2 and a base 3. The table 1 is arranged in a partially shown vehicle, here a train wagon, on a vehicle side wall 100 of the vehicle. A longitudinal axis A of the table 1 extends parallel to the longer side edges 4 of the tabletop 2 and is transverse to a direction of travel 101 of the vehicle. The base 3 has an essentially vertical wall part 5 lying against the vehicle side wall 100 and a substructure 6 directly below the table top 2 . The tabletop 2 projects beyond the substructure 6 in sections at the side edges 4 and thus forms two widespread impact surfaces 7 on each side. Two seats 102 are arranged on both side edges 4 of the tabletop, two in and two against the direction of travel 101. The impact surfaces 7 arranged directly in front of the seats 102 along the direction of travel 101 and thus offer a larger area where passengers can collide with the table 1 in the event of a collision.

Auf Höhe der Tischplatte 2 weist das Wandteil 5 an der Fahrzeugseitenwand 100 einen zur Tischplatte 2 zeigenden, leicht abgerundeten Bereich auf, an der eine Breitkante der Tischplatte 2 anliegt. Diese Breitkante hat ebenso eine darauf abgestimmte, abgerundete Form. Ist nur einer der Sitzplätze 102 in Fahrtrichtung besetzt und kommt es zu einem Zusammenstoß, so kann sich damit die Tischplatte 2 in Bezug zum Sockel 3 leichter verdrehen, ohne dass es zu Beschädigungen des Sockels 3 oder der Tischplatte 2 kommt.At the height of the table top 2, the wall part 5 on the vehicle side wall 100 has a slightly rounded area pointing towards the table top 2, against which a broad edge of the table top 2 rests. This broad edge also has a coordinated, rounded shape. If only one of the seats 102 in the direction of travel is occupied and a collision occurs, the table top 2 can rotate more easily in relation to the base 3 without the base 3 or the table top 2 being damaged.

In Fig. 2 wird der Sockel 3 in einer Explosionsdarstellung gezeigt. Zur besseren Übersicht wurden dabei einige Bauteile wie Schrauben nicht oder nur teilweise dargestellt. Das Wandteil 5 des Sockels 3 ist aus hochfestem Stahl und/oder Aluminium hergestellt und erfüllt hauptsächlich die Aufgabe der statischen Halterung des Tisches 1. Es besteht aus einer an der Fahrzeugwand 100 anliegenden, der Kontur der Fahrzeugwand 100 entsprechenden Platte, sowie Seitenteilen. Der Unterbau 6 weist eine Hülle 8 aus Stahlplatten und/oder Aluminiumplatten auf, wobei auf der der Tischplatte 2 zugewandten Seite zwei mit Öffnungen versehenen Hüllenplatten 9 angeordnet sind. Im Inneren des Unterbaus 6 ist eine Verbindungsvorrichtung 10 angeordnet, welche einen Verbindungsbalken 11 aufweist, der als Blattfederpaket ausgeführt ist, sich im Wesentlichen entlang der Längsachse A erstreckt und in einem unbelasteten Zustand dargestellt ist. Dabei zeigen die Flächen der Blattfedern in oder gegen die Fahrtrichtung, die elastische Verformung ist also in oder gegen die Fahrtrichtung am besten möglich. Diese Verbiegungen quer zur Längsachse A und damit in oder gegen die Fahrtrichtung sind schematisch durch Linien 21 angedeutet.In 2 the base 3 is shown in an exploded view. For a better overview, some components such as screws were not shown or only partially shown. The wall part 5 of the base 3 is made of high-strength steel and/or aluminum and mainly fulfills the task of static support of the table 1. It consists of a plate lying against the vehicle wall 100 and corresponding to the contour of the vehicle wall 100, as well as side parts. The substructure 6 has a shell 8 made of steel plates and/or aluminum plates, with two shell plates 9 provided with openings being arranged on the side facing the table top 2 . A connecting device 10 is arranged inside the substructure 6, which has a connecting beam 11, which is designed as a leaf spring assembly, extends essentially along the longitudinal axis A and is shown in an unloaded state. The surfaces of the leaf springs point in or against the direction of travel, so elastic deformation is best possible in or against the direction of travel. These bendings transversely to the longitudinal axis A and thus in or against the direction of travel are indicated schematically by lines 21 .

Mittig entlang seiner Länge weist der Verbindungsbalken 11 einen Befestigungsbereich 12 auf, der mit einem Querbalken 13 des Unterbaus 6 fest verbunden ist. An den Enden des Verbindungsbalkens 11 sind Verbindungsstücke 14 mit zur Tischplatte 2 zeigenden Langlöchern angeordnet. Die Langlöcher erstrecken sich im unbelasteten Zustand des Verbindungsbalkens 11 entlang der Längsachse A und damit entlang der Länge des Verbindungsbalkens 11. Verbindungsstifte der Tischplatte 2 können in diese Langlöcher eingreifen und damit eine Verbindung herstellen. Das Blattfederpaket wird mit insgesamt vier Klammern zusammengehalten, zwei an jeder Seite des Verbindungsbalkens 11. Die Klammern sind dabei beweglich am Blattfederpaket angeordnet. Die Klammern sind über einen Gewebestreifen zusammengehalten, der als Positionierhilfe wirkt und sowohl mit den Klammern, als auch mit dem Querbalken 13 und den Verbindungsstücken 14 verbunden ist.In the middle along its length, the connecting beam 11 has a fastening area 12 which is firmly connected to a cross beam 13 of the substructure 6 . At the ends of the connecting beam 11 connecting pieces 14 are arranged with the table top 2 pointing slots. In the unloaded state of the connecting beam 11, the elongated holes extend along the longitudinal axis A and thus along the length of the connecting beam 11. Connecting pins of the tabletop 2 can engage in these elongated holes and thus create a connection. The leaf spring assembly is held together with a total of four brackets, two on each side of the connecting beam 11. The brackets are movably arranged on the leaf spring assembly. The brackets are held together by a strip of fabric which acts as a positioning aid and is connected to the brackets as well as to the crossbeam 13 and the connecting pieces 14.

Der Querbalken 13 weist eine Führung auf, in der ein quer zur Längsachse A beweglicher Schlitten 15 angeordnet ist. Dieser weist eine Öffnung auf, in die ein Verbindungsstift der Tischplatte 2 eingreifen kann. Vorzugsweise ist der Verbindungsstift mittig an der Tischplatte 2 angeordnet.The crossbeam 13 has a guide in which a slide 15 movable transversely to the longitudinal axis A is arranged. This has an opening into which a connecting pin of the tabletop 2 can engage. The connecting pin is preferably arranged centrally on the table top 2 .

An den Enden des Unterbaus 6 ist je eine Federstange 16 vorgesehen, die gefedert in Richtung der Tischplatte 2 gedrückt werden. Die Hüllenplatten 9 weisen Durchtrittsöffnungen 17 auf, durch die die Federstangen 16 hindurch auf die Unterseite der Tischplatte 2 gedrückt werden können. Die Federstangen 16 sind dabei an ihrer Oberseite mit einer reibenden Schicht wie etwa einer Filzschicht überzogen, die die Bewegungen der Tischplatte 2 dämpfen. Diese reibende Schicht kann auch auf der Unterseite der Tischplatte 2 angeordnet sein. Damit wirken die Federstangen 16 als Reibelemente. An den Enden des Unterbaus 6 entlang der Längsachse A ist auch je ein Sekundärelement 18 angeordnet, welches sich im Wesentlichen quer zur Längsachse A erstreckt. Sie weisen je zwei Endstücke 19a, 19b in Form von Zapfen auf, welche an Auflageflächen der Hülle 8 des Unterbaus 6 quer zur Längsachse A anliegen.A spring rod 16 is provided at each end of the substructure 6 and is pressed in the direction of the table top 2 in a spring-loaded manner. The cover plates 9 have openings 17 through which the spring rods 16 can be pressed onto the underside of the table top 2 . The upper side of the spring rods 16 is covered with a rubbing layer, such as a felt layer, which dampens the movements of the table top 2 . This rubbing layer can also be arranged on the underside of the table top 2 . The spring rods 16 thus act as friction elements. At the ends of the substructure 6 along the longitudinal axis A there is also a secondary element 18 which extends essentially transversely to the longitudinal axis A. They each have two end pieces 19a, 19b in shape of pins, which lie transversely to the longitudinal axis A on bearing surfaces of the shell 8 of the substructure 6 .

In Fig. 3 wird die Funktionsweise der Verbindungsvorrichtung 10 ersichtlich. Dazu wurde eine der Hüllenplatten 9 nicht dargestellt. Auf jedem Endstück 19a, 19b ist je ein Auflagestück 20 aufgesteckt, welches S-förmig aufgebaut ist, und sich von dem Endstück 19a, 19b, mit dem es in Verbindung steht, an der Seite des Sekundärelements 18 bis über die Hälfte der Länge des Sekundärelements 18 erstreckt. Die Auflagestücke 20 weisen dazu Öffnungen auf, in die die zapfenförmigen Endstücke 19a, 19b eingreifen können (ersichtlich in Fig. 2). Die Verbindungsstücke 14 weisen auf der zu den Sekundärelementen 18 zeigenden Seiten Anker 22 auf, die im unbelasteten Zustand der Tischplatte 2 Angriffshaken 23 der Auflagestücke 20 nicht berühren. Das Verbindungsstück 14 und Anker 22 sind einstückig sowie die Angriffshaken 23 und Auflagestücke 20 auch einstückig ausgeführt. Diese Auflagestücke 20 sind entlang der Längsachse A auf Höhe der Angriffshaken 23 aber beabstandet von diesen angeordnet. Wird die Tischplatte 2 in eine Richtung B bewegt, beispielsweise durch den Aufprall von bis zu zwei Passagieren, so wird der Verbindungsbalken 11 in eben diese Richtung elastisch verbogen. Bei nur geringer Verbiegung bleiben die Sekundärelemente 18 unverändert. Ist die Verbiegung so stark, dass die Anker 22 je einen der Angriffshaken 23 erreichen, die mit ersten Endstücken 19a verbunden sind, so wird die Verbindung zwischen Tischplatte 2 und Sekundärelement 18 geschlossen. Die ersten Endstücke 19a werden dadurch in Richtung der zweiten Endstücke 19b gedrückt, welche an dem Unterbau 6 anliegen und nicht bewegbar sind. Damit kommt es durch die weitere Bewegung der Tischplatte 2 zu einer elastischen Verformung der Sekundärelemente 18. So wird neben der Verbindung über den Verbindungsbalken 11 parallel dazu eine weitere Energie aufnehmende Verbindung zwischen Tischplatte 2 und Sockel 3 geschaffen. Bei der Bewegung der Tischplatte 2 in die entgegengesetzte Richtung verhält sich die Verbindungsvorrichtung 10 im Wesentlichen analog, wobei die Angriffshaken 23 verwendet werden, die mit den zweiten Endstücken 19b in Verbindung stehen.In 3 the functioning of the connecting device 10 becomes apparent. For this purpose, one of the shell plates 9 has not been shown. On each end piece 19a, 19b a support piece 20 is attached, which is constructed in an S-shape and extends from the end piece 19a, 19b, with which it is connected, on the side of the secondary element 18 to over half the length of the secondary element 18 extends. For this purpose, the support pieces 20 have openings into which the pin-shaped end pieces 19a, 19b can engage (seen in 2 ). The connecting pieces 14 have anchors 22 on the side pointing towards the secondary elements 18 which, in the unloaded state of the table top 2, do not touch the gripping hooks 23 of the support pieces 20. The connecting piece 14 and anchor 22 are made in one piece, and the gripping hooks 23 and support pieces 20 are also made in one piece. These support pieces 20 are arranged along the longitudinal axis A at the height of the gripping hooks 23 but at a distance from them. If the table top 2 is moved in a direction B, for example due to the impact of up to two passengers, the connecting beam 11 is elastically bent in precisely this direction. If the bending is only slight, the secondary elements 18 remain unchanged. If the bending is so severe that the anchors 22 each reach one of the attachment hooks 23 which are connected to the first end pieces 19a, the connection between the table top 2 and the secondary element 18 is closed. The first end pieces 19a are thereby pressed in the direction of the second end pieces 19b, which bear against the base 6 and cannot be moved. The further movement of the table top 2 thus results in an elastic deformation of the secondary elements 18. In addition to the connection via the connecting beam 11, another energy-absorbing connection between the table top 2 and the base 3 is created in parallel. When moving the table top 2 in the opposite direction, the connecting device 10 behaves essentially analogously, using the engaging hooks 23 which are connected to the second end pieces 19b.

Prallt nur eine Person außermittig auf die Tischplatte 2 auf, so kommt es durch die ungleiche Kraftbeaufschlagung zu einer Verdrehung der Tischplatte 2 oder einer sich überlagernden Bewegung von Verdrehung und Verschiebung.If only one person hits the table top 2 off-centre, the unequal application of force causes the table top 2 to rotate or a movement of rotation and displacement superimposed.

Das Sekundärelement 18 ist zweiteilig als innen gefederter Stoßdämpfer aufgebaut.The secondary element 18 is constructed in two parts as an internally sprung shock absorber.

Die in den Figuren beschriebene Ausführungsform ist für eine 4-Personen-Sitzgelegenheit ausgeführt, sodass also zwei Personen in und zwei Personen gegen Fahrtrichtung am Tisch sitzen. In einer alternativen Ausführungsform kann vorgesehen sein, dass nur eine Person in und eine Person entgegen der Fahrtrichtung sitzt. Dem entsprechend ist der Tisch kleiner ausgeführt, wobei vorzugsweise im Wesentlichen die gleiche Technologie verwendet werden kann, gegebenenfalls mit entsprechenden Adaptionen und Anpassungen. Dabei kann nur eine Hälfte des Tisches ausgeführt werden, sodass der Querbalken 13 an der Fahrzeugseitenwand 100 angeordnet wird und sich der Verbindungsbalken 11 nur in einer Richtung vom Querbalken 13 aus erstreckt. Dem entsprechend wäre dann vorzugsweise auch nur ein Sekundärelement 18 vorgesehen. Alternativ kann auch der gleiche Innenaufbau wie in den Figuren gezeigt vorgesehen sein, jedoch entlang der Seitenkanten 4 in kürzerer Ausführungsform, sodass an jeder Seitenkante 4 nur ein Sitz angeordnet wird. Prinzipiell besteht auch die Möglichkeit, Tische mit mehr als zwei Sitzplätzen in Fahrtrichtung, also mit drei oder vier Sitzplätzen vorzugsehen.The embodiment described in the figures is designed for a 4-person seat, so that two people sit in and two people against the direction of travel at the table. In an alternative embodiment it can be provided that only one person in and one person against the direction of travel sits. Accordingly, the table is made smaller, it being possible for essentially the same technology to be used, if necessary with appropriate adaptations and adjustments. In this case, only one half of the table can be implemented, so that the crossbeam 13 is arranged on the vehicle side wall 100 and the connecting beam 11 only extends in one direction from the crossbeam 13 . Accordingly, only one secondary element 18 would then preferably also be provided. Alternatively, the same internal structure as shown in the figures can also be provided, but in a shorter embodiment along the side edges 4 , so that only one seat is arranged on each side edge 4 . In principle, there is also the possibility of tables with more than two seats in the direction of travel, i.e. with three or four seats.
